All subject librarians classify their own subject, preferrably by pre-classification

We use webdewey (DDC23) – and look forward to the Norwegian version!

We contribute to an existing DDC subject register at UHS

We use the number building tool in webdewey, share numbers across the institution, and also contribute our built numbers

We are using our own controlled subject vocabulary which we are currently exploring how to map to DDC How do we organise our work with classification? There is still work to be done

The general skepticism towards a new classification system has diminished

A common system makes it easier to work together as a unit

Payoff for users and employees! Conclusion DDC23 is currently sparsely developed on geosciences

We have a broad collection in some fields that have to fit into a small range of numbers, e.g. pharmacy (a separate institute at UiO), biochemistry

We look to other universities, but we need a larger network

We use OCLC Classify (http://classify.oclc.org), but we do not always agree Some complications to conquer A lot of tidying!

Leaving the old subject specific collections as they were

Starting a new cross-discipline collection including all the subjects

Classification and shelf marking according to DDC23 What did we do? From multitude to unity Introducing DDC to the Science Library DDC is a system that is currently being updated, and also translated into Norwegian (Norsk Webdewey)

It includes all our subjects

Our big brother Humanities and Social Sciences Library (UHS) uses DDC

Two of our collections already had DDC classifications

Classification can more easily be done by other persons than the subject librarian for the specific subject

DDC is not specific enough in some subjects (creative number building…)
